User Reviews

Users broadly praise the app for useful, time-saving Ohm's law and conversion calculations and the developer’s responsiveness. However, recurring issues with licensing/pay prompts, occasional crashes, and UI glitches hurt the experience. Some reviewers question calculation accuracy and find certain tasks less intuitive (e.g., parallel resistors) compared with web tools. Overall value is seen by many, but reliability and consistency need improvement.
Pros
  • Very useful for electricians and quick calculations
  • Broad set of electrical conversions/calculations with a simple, easy-to-use UI
  • Developer is responsive and actively improves the app based on feedback
  • Time-saving for circuit/relay calculations
  • Good value for money / affordable price
Cons
  • License/paywall issues after purchase: app remains locked, prompts to pay again, and poor support or responsiveness from the developer
  • Stability issues: app frequently crashes or closes during use
  • UI/UX problems on mobile: keyboard/input overlays obscure results and formulas on screen
  • Possible inaccuracies in Ohm's Law expressions within the app (mislabeling or incorrect relationships)
  • Some tasks (e.g., parallel resistor calculations) are not as intuitive and may be easier with web calculators

Ive had the app for a while now and its definitely come a long way and its looking great. I’m a journeyman electrician and the app has been very useful. The dev is also really great at responding to feedback and making improvements. Highly recommend, for less then a coffee its a great deal.

Just trying to calculator multiple resistors in parallel. Thought I used to be able to use this app. Could figure it out now. Went to web based calculator which was much easier.
